HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 520,911, dated J' une5,1894.

Application filed February 23, 1893. Serial No. 463.295. (No model.)

` To a/ZZ whom iv' may concern.-

Be it known that I, EDWARD E. ASHLEY, a citizen of the United States,residing at New York, in the county of New York and State of'New York,have made certain new and useful Improvementsin Heating Apparatus, ofwhich the following is a specification.

My invention relates to independent or isolated heating devices, andcomprises a suitable generator, a coil for circulating steam or hotwater leading from the generator and returning thereto, and devices forsupplying" the generatorwith Water and for interchangeably using thedevice for hot water or steam circulation.

generator, I have shown devices for utilizing those mediums.

My invention further consists of the details of structure hereinafterdescribed and further pointed out in the claims.

In the accompanying drawings forming part of this specification-Figure 1is a sectional elevation of the generator and radiator, with an oilburner secured under the generator for the purpose of heating the sameby oil; Fig. 2, a plan and cross section of Fig. 1, taken approximatelyon the line a: a: of that gure; Fig. 3, a bottom view of the generatorwith the burner removed; Figs. 4 and 5, respectively, plan views of themetallic and asbestus gaskets; Fig. 6,"a diagrammatic view showing adevice for automatically regulating the amount of heat supply to thegenerator and thereby the temperature of the hot water or the pressureof steam in the regulating and circulating coil.

Like numerals ,of reference refer to like parts in all the views.

In the drawings lis a cast iron base of any suitable form orconstruction, and upon this is mounted a preferably circular jacket 2having perforations 3 therein, the jacket being secured upon the base bythe angle iron 4.

The generator consists of a cast iron shell 6 having at the bottom anannular dome 7 a having a ledge 7. The shell is provided with lugs S ateach side (see Fig. 3) by means of which the generator is bolted to thetop plate 9 of the base 1 by means of the bolts 10. Dependingfrom thebottom 11 of the shell 6 are ears 12 against which abut ears 13depending from the top plate 9 of the base 1. Secured within the dome 7is a circular and preferably convex crown sheet 14: of copper so as toreadily transmit the heat, and between the metal and the ledge 7 and thecrown sheet is interposed an asbestus gasket 15 provided' with a seriesof holes 16, and below the crown sheet lies a collar 17 likewiseprovided with holes 18, the gasket 15, crown sheet 14 and collar 17being secured in the dome 7?' by means of the nut bolts 19 which passthrough the holes in both the collar and gasket. The crown sheet is thusdetachably secured, so that it can be readily removed if burned out.

The circulating and radiating coil comprises a vertical stand pipe 2Owhich enters the top of the shell 6 in the usual way, and connects bymeans of an elbow 21 with the sections 22, 23 united by the elbows 24,the sections 22, 23 and elbows 24 being'continued downwardly in turnswhich return to the generator through the elbow 25 and short pipe 26.

The particular form of coil and the configuration of the generator isimmaterial, except that I desire to use a vertical riser 20, and let thehot water or water of condensation return by gravity to the generator,the return inlet being below the top of the shell 6.

It it is desired to use oil as a heating rnedium, af multi-wick lamp,such as shown in Fig. 1, can be used, which comprises the reservoir 27having the burners 28, and filling vent 29 which is secured by arms 30to both the ears 12 and the ears 13 by means of the bolts 31 which passthrough them. -A pet cock 32 secured to one of the turns of theradiating coil extends from without the jacket, and can be used for thepurpose of 'testing the coil for steam or water.

It is apparent that if heat is applied to the crown sheet of thegenerator, the water there- IOO the following: Secured to the top ofthejacket.

is a tank 33 of any suitable size, which extends above the top of thecoil, the tank and the shell 6 being connected by a stand pipe 34which`enters the top of the shell in the usual way.` It is apparent that ifwater is poured into the tank, which water has a sufficient head,it williow into the shell up into the stand pipe 20, then downward through thet turns of the coil, back to the generator again, completely iillingboth the coil and the gen- `erator, after which connection between thetank and the generator can be closed by means of the valve in the pipe34. The pipe 34 is located within the coil and becomes heated byradiation therefrom, and to supply warm or cold water, as before setforth, the pipe 34 and tank are filled with water, the valve 35 closedand the water therein permitted to remain long enough to become heated,when the valve 35 can be opened and a fresh supply of warm waterfrom thestand pipe and tank 33 can besupplied to the generator.` The tank 33 canbe put in direct communication with a regular l source of supply bymeans of the pipe 36, in which a valve 37 is interposed, or a funnel 38can be used, as shown, to eitherconstantly supply water or to give asupply of water, and controlled by the valve 37, to make ,np for` theloss of water by evaporation or leaking. As will be seen from Fig. l thetank "33 is closed, except when the valve 37 is opened to permit of theentry of Water. If steam is to be used as a heating and radiatinglnedium then the cock 35 in the stand pipe 34 will be closed. It a hotwater circulation is to be used then the pipe 34will be filled withwater and the cock 37 closed.

" If it is desired to use only heated water as a circulating medium, thegeneration of steam can be prevented by using gas or oil burners ofsuiicient size to only heat the water to make it circulate; but if steamis to be used tomatic device which will regulate the temperature.`Instead, however, of regulating the temperature by means of theparticular sizeof burner, as before described, when hot water is used, Ican use an automatic device.

forthis purpose also.` This device I have illustrated with the use ofgas as a heating medium.

halves or sections 40, 41 and an interposed` flexible diaphragm 42 towhich diaphragm a toggle rod 43 is connected by a pin 44, the rodpassing through a stuffing box 45, the two sections 40, 4l and thediaphragm being bolted together, as shown, by the bolts 46.

48 leads to a suitable burner 49 to supply gas or other like heatingmedium, and interposed in the pipe 48 is a Valve casing 49, the valvestem 50 of its valve being connected to the rod 43 by a lever lhavingasegmental slot 52, and through thelslotiand rod 43 passes a set screw53, so that by movingthe set screw and arm 43 in the slot 42 the samecan be adjusted therein to give the lever 5l var ing throws, and thevalve in the Valve casing 49 any desired degree of movement and increaseor decrease the `supply of gas or other heating medium. Should itbedesired to heat the water to a degree at whichsteam is generated, theburners being capable of combusting enough of the gas or other mediumfor this purpose, the play of the lever 5l can be regulated so as tosupplyl enough gas to generate steam. Ii' hotwater is only to be made,the relation of the rods'43 and 51 can be adjusted so as to supply butsufficient heating medium for this purpose." It is also plain that theregulator can be'used for burners for hydrocarbon oils as -well as gas.

I-Iaving thus described my invention, I claiml. `The combination withthe shell 6, of the dome 7L having an aperture therein, the crown sheet14 lying within ther aperture, a nencombustible gasket between the crownand the dome, the crown sheetand the gasket being secured to the dome,substantially as described.

The generator shell 6 `having the` ears 8 secured to a suitable base9,` the dome 7, crown sheet 14 secured within the dome, the stand pipe20 arising from the shell, the re turn sections of the coilentering theshell below its top, and a heating device suspended below thecrownsheet, substantially as described.

3. AThe combination with the generator shell G, of the dome 7a risingtherein, anda crown sheet 14 detachablysecured within the dome,substantially as described.

4. The combinationwith the generator, of the base havingan openingtherein for the reception of the generator, adomewithin the generator,the detachable crown `sheet within the dome, a circulating and radiatingcoil comprising the stand pipe20having `its exit from the top of thegenerator, anda series of descending coil sections returning tothegenerator below the exit ot' the pipe 20, aburuer IOO- supported belowthe generator, and a water dome, both the crown sheet and gasket beingxo supply pipe for the generator, substantially detachably securedwithin said dome, subas described.

5. In a heating apparatus, the combination with the generator shell 6having an opening in the bottom 11 thereof, a dome rising from saidbottom around said opening a convex crown sheet 14, and a non-conductinggasket interposed between the crown sheet and the stantiaily asdescribed.
